The coupling of electrons to a bosonic field generally causes a renormalization of the energy levels. Whereas in vacuum, the electromagnetic fluctuations lead to the Lamb shift observed in the hydrogen atom levels, in condensed matter, the phonon field renormalizes the band structure, even at zero temperature. Being as large as several hundreds of meV, this renormalization is critical to the...

Spectacular experiments have demonstrated the controlled layer-by-layer growth of
oxide heterostructures. This leads to the exciting prospect
of tuning magnetism and topological states of correlated electrons in low dimensions. Here, we model
$\{111\}$-grown bilayers of spin-orbit coupled double perovskites such as Sr$_2$FeMoO$_6$, showing
that these buckled honeycomb materials act as...

Graphene quantum dots (GQDs) with engineered lateral size, shape, and edge allow for the modification of the electronic, optical and magnetic properties of graphene [1-5]. Here we present a theory of optical properties of GQDs [2-5]. Building on our previous work [1-4] we expand the single-particle wave functions in Pz carbon orbitals and compute energy spectra using the tight-binding model....

Invited Speaker / Conférencier invité
Phase field crystal models and their recent extension to periodic order parameters will be summarized. Their application to new results in non-equilibrium kinetics and phase transformations in materials science will be reviewed. In particular, we review new results from applications of this modeling paradigm to solute trapping during rapid solidification of alloys, defect-mediated solid-state...

We develop a model of liquid crystalline homopolymers using self-consistent field theory (SCFT) for semiflexible spherocylinder-shaped particles that can form the isotropic (I) phase, the nematic (N) phase and the smectic-A phase (SmA). As in previous work by Chen [Macromolecules 26, 3419 (1993)] and Duchs and Sullivan [J. Phys. Cond. Mat. 14 12189 (2002)] we employ the excluded volume...

We examine the kinetics of phase transitions in AB diblock copolymer melts using a dynamical self-consistent field theory that we recently developed. By applying the variational priniciple to an appropriate dynamical functional integral, which is based on the exact microscopic polymer dynamics, we obtain the self-consistent equations. These equations are then solved through an ensemble of...
